BOLSTER FOR RAILWAY-CARS.

SPECIFICATION forming part'. Of Letters Patent N0. 694,385, dated March 4, l 902.

Application tiled July 13,1901.

T @ZZ w/"wm, it may concern,.-

Be it known that we, FRANK S. INGoLDsBY and JOSEPH R. BOWLING, citizens of the United States, residing at St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Bolsters for Railway-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

.The object of this invention is to provide a steel bolster for railway-cars which while being cheap to construct shall be very light, strong, and rigid in operation.

Our bolster is particularly designed for use with steel cars and may be convenient-ly employed in steel dump-cars.

The invention may be best summarized as consisting of the combinations of elements hereinafter described, and definitely set out 2o in the claims.

The drawings clearly illustrate a bod y-bolster having our invention, Figure l being a side elevation of a little more than half thereof; Fig. 2, a bottom plan of the same, and Fig. 3 a top plan thereof. Fig. 4 is a vertical central section through-the bolster. Fig. 5 is a vertical section on the line 5 5 of Fig. 1 looking toward the center of the bolster. Fig. 6 is a similar section on the line 6 6 of Fig. l. 3o Fig.7 is a top view of the center bearing. Fig. 8 is a horizontal section on the line 8 8 of Fig. l.

The same letters of reference designate the same part in each ligure.

As shown in the drawing, our bolster includes a central box-like casting or frame A, a compression member B, extending diagonally downward across the lower end of the frame, and a tension member C, extending 4o diagonally upward across the upper end of the frame, the extreme ends of the members C and B being secured together. The central frame A is of the form shown, having a horizontal top plate a and a horizontal bottom plate al and vertical side plates a2 a2. These parts are all strengthened by a pair of webs da. The compression member B lies in contact with the under side of the plate a and is riveted thereto by the rivets d. This ing E, riveted to the flanges of the channel Serial No. 68,128. (No model.)

plate a' has its edges flanged downward, as at a4, making, in effect, a shallow inverted channel at the base of the frame, in which takes the compression member B. The tension member C is a flat plate lying in contact with the upper side of the plate aand riveted thereto. The extreme ends c of the tension member are turned downward across the ends ot' the channel member B. Within the channel member, nearits end, is the reinforcing-cast- 6o member by the various rivets d2. This casting E is in the form of an inverted box, as shown, having atop plate and side and end flanges, the outer end ilangeecontacting the downturned end c' ofthe tension member and the two being riveted together by the rivets d3. A filling-block F lies between the compression and tension members at their ends, and the parts here are all bound in place by the rivets d4 d5, which pass through the tension, member, the filling-block, the compression member, and the reinforcing-casting E. The arrangement of these cooperating parts at the end of the bolster, as above described, has many advantages. It materially stiifens the end of the bolster and greatly aids in preventing the same from bending downward, due to the weight of the superincumbent side of the car. It obviates the necessity of bending the channel member B, which would be difficult. It distributes the thrust to the web and both flanges of this channel member. It provides convenient surfaces for the reception of various rivets desired. It lessons the liability of the tearing apart of the end of the bolster, as the filling-block F allows the rivets d4 to take a shearing strain only instead of having both a shearing and tension strain as they would if this filling-block were omitted. The result of these various features is that a particularly strong, light, and efficient construction is provided.

The drawing shows a channel-shaped side sill G and an inclined side strut H, riveted together and both resting on the tension member C and held in place by the rivets d5, passing through flanges of these members in addition to the tension member, the fillingblock, thecompression member, audits ,refy

inforcing-block,asshown. Thearrangement of the side sill and the side strut, however,

is shown simply as illustrative and is not aH portion of this invention.

A Between the filling-block F and the center casting A we brace the ybolster by a suitable intermediate vertical strut.` As shown, thisV strutvconsists of the horizontal beam J, passing diagonally through thebolster, theffilling-block K above it, and the fillingblock L below it. Rivets d6 pass through the tension member C, the filling-block-K, and 'the liange of the beam J, which is preferably an I-beam, binding these parts together, whileV below rivets d? secure. the -IK-beam to the ill-V ingblock L, and rivets d8 secure the latterfilling-block` to the compression member B. These latter rivets also hold in place the side bearing M, which is a casting seating .within the channel B. The block L is preferably cored, as indicated, having top and bottom` member `C and thelilling-block K by a connection-plate p, which seats within the tilling-block and is pierced by some of the rivets d6. The bolster is still further strengthened by a pair of tension-rods Q, secured at one end to the central casting A by the bolts R, which pass through that casting and have on their ends nuts r, which clamp eyesin the ends ot the bars Q, which surround the bolts. The other ends of these bars Q takediagonally through the filling blocks L, through the compression members B beneath the same, and through the side bearings M and are adjnsted by nuts q, bearing against those side bearings. The simple tightening of these latter nuts would thus true up the bolster, if any derangement of the car should cause the side bearings to sag.

' The center bearing, which seats in the channel member B, is a channel-shaped block S, having the top plate and side fianges s and at its center the cylindrical boss s2. The boss has a horizontal lower face s4 and an inner tubular walls3 and four internal crosswebs S5, which come directlyr beneath the Webs a3 of the central frame, whereby the strains due to the weight of the load are transmitted directly through those webs. The peripheral face s2 and the horizontal face s4 of the boss form the rubbing-surface for the corresponding member in the truck-bolster. A king-pin T occupies the tube s3 and projects up into the castingA between the webs a3 thereof and is there locked by a key t. The drawing shows vertical plates U vlying against the outer surface of the sides d2 of the center casting and riveted thereto by the rivets (lf2. These plates extend toward the end of the car, forming the dra-ftbeam. They are shown also as extending while, at its npper edge the plate is also` se.-

cured to the side of an nppervcord of the center truss. yThis -upper cord, as shown, consis-tsfof the inverted channel-beam Y, snrmounted by the invertedflbeam W, the plate U being riveted to the channel-beam. As

shown, these beams W and V project into the.

bolster beneath the tension member C (the flangeof the T-beam being removed) andare theresiipported by the bracket Y, which is held to the casting bysome of the saine riv;

ets d? which hold the side plates E. The.

drawing, Figs. 4 and 5, also show an inclined tension member Z, which is the en d of the lower chord of the trussed center. This tension member hasitsupper end horizontal, extending aciossthebracketY,and being gibbed up across the end of the channel V and the T-beam, as shown at z. Y

The above arrangement of trussed center beam and the platesU is not a part ofthe present invention, but is illustratedherein to show how these parts may be connected to the bolster. l
